“…For Agriculture sector, companies can increase the utilization efficiency of pesticides and agricultural plastic films with circular agriculture (Cansado et al, 2022). They can also deploy advanced technologies like trickle irrigation (Khalifa, 2022) and carbon sequestration in agricultural land (Johansson et al, 2022) to save the input resources and improve the accessibility of financial support to accelerate the environmental‐friendly transition in agriculture. Second, improving production efficiency could also help to reduce the environmental impact of sectors driven by the final demand of finance of business sector.…”

The global finance and business is a trillion-dollar sector whose final demand drives a significant amount of economic production and services in other sectors through trade systems. As economic production and services have a significant impact on the environment, they play a fundamental role in supporting the global sustainable development goals (SDGs). Despite this, little attention has been paid to environmental impact driven by the final demand of global finance and business sector (i.e., environmental footprint). In this paper, we estimated the carbon dioxide (CO 2 ), sulfur dioxide (SO 2 ) and particular matter 10 (PM 10 ) footprints of finance and business sector of 187 economies from 2000 to 2016 using a global multi-regional input-output model. Our results show that global environmental footprints peaked 10 years ago, and the latest CO 2 , SO 2 and PM 10 footprints are approximately 1371, 8.2 and 6.1 million tons, respectively. We also found that 99% of environmental footprints originate from 20% economy-sectors, and the critical economy-sectors are identified. In addition, policy interventions on environmental intensity, production efficiency and trade network for mitigating the environmental footprints are proposed as well. Our findings provide a holistic and dynamic picture of the environmental footprints of the global finance and business sector.

High costs associated with technology adoption can be a barrier against the improvement of water use in agriculture. Therefore, interventions must be not only technically feasible but also financially affordable and accessible to farmers. To understand the current situation of research in lowcost (and cost-effective) water solutions for effective management of agricultural water challenges in Egypt. A total of 19 peer-reviewed papers were obtained from systematic research on various databases, the employed keywords are: “Egypt” AND “irrigation” AND “low cost” OR “low-cost” OR “cost-effective” OR “cost-effective”. Based on the analysis of the selected studies, many low-cost technologies and techniques are applied in the Egyptian Delta on-farm levels, such as using low-cost soil moisture sensors attached to a smart monitoring unit operated by Solar Photo Voltaic Cells (SPVC), wireless sensor network in cultivating the potato crop, flexible on-field irrigation, cut-off irrigation, and Pressurized Irrigation Systems. The proposed solutions can help improve water use efficiency, increase crop yields, reduce the cost of irrigation, improve the quality of irrigation water, and promote sustainable agricultural practices. The economic analyses and feasibility studies presented in these papers provide valuable insights for policymakers and stakeholders in making informed decisions about water use and agricultural practices.

This research aims to study the effect of land surface slope on the shape and size of the wetting pattern in the soil resulting from a dripping source, especially when there is a local surface runoff resulting from a water application rate higher than the soil infiltration capacity. As a result, it leads to a noticeable displacement of the center of the wetting pattern from the emitter position. The present research included finding this displacement mathematically and verifying its validity with the results of laboratory data. The studied data included 85 overlapping cases of the change in the water application rate and the slope of the soil surface for two levels of initial moisture and two soils of different textures. The results showed that the first devising equation could be used to estimate the wetting pattern center displacement from the emitter, resulting from the slope of the soil surface. The usage of the first devising equation was based on the of half the maximum horizontal surface advance (a), the maximum vertical advance under the emitter (b), and the soil surface slope, especially when the ratio (a/b) was within (0.9-1.1). The second devising equation can estimate the wetting pattern center displacement from the emitter resulting from the soil surface slope, regardless of the (a/b) ratio. That is, there was a considerable convergence between the displacement values of the center of the wetting pattern from the emitter position estimated by the first devising equation and the second devising equation when the value of (a/b) was close to one, which represents 87% of the 85 cases covered in this research.
